ITEM 2.       ACQUISITION OF ASSETS.

         On February 17, 1998, Osmonics, Inc. (the "Company") completed the
acquisition of all of the shares (the "Acquired Shares") of Micron Separations,
Inc., a New York corporation ("MSI"). MSI, located in Westborough,
Massachusetts, is a developer, manufacturer and marketer of microfilter membrane
products for laboratory, diagnostic, and industrial use. MSI revenues were less
than $15 million in each of the last three years.

         MSI filed a voluntary petition for reorganization under Chapter 11 of
the Bankruptcy Code in the United States Bankruptcy Court for the District of
Massachusetts on April 9, 1997, Case No. 97-42342-JFQ. On December 15, 1997,
pursuant to Chapter 11 of the Bankruptcy Code, MSI and the Company submitted a
Joint Plan of Reorganization (the "Plan"). The Plan was confirmed by the United
States Bankruptcy Court on January 28, 1998. Pursuant to Article VII of the
Plan, MSI's existing equity securities were canceled and Osmonics received the
Acquired Shares. The Acquired Shares consist of 1,000 shares of common stock of
the reorganized MSI, which represents 100% of the outstanding voting securities
of MSI.

         Under the Plan, Osmonics will provide up to $28 million (in addition to
MSI's cash),for the payment in full of all MSI's creditors and payment to
holders of MSI's equity securities. The aggregate consideration to be paid to
holders of MSI's equity securities will not exceed $15,200,000 which amount
will be adjusted based upon the final amount of claims of MSI's creditors under
Section 1.16 of the Plan and, pursuant to Section 3.5 of the Plan, is subject to
set-off rights and a hold back of 10% of the consideration finally determined to
be payable to such holders. In addition, pursuant to Section 3.5(c) of the Plan
holders of MSI's equity securities are entitled to receive the amount, if any,
of any recovery in a certain lawsuit, less expenses.

         On February 17, 1998, the Company pursuant to the Plan paid James S.
Johnson and John Greenwood, both founders and significant shareholders, and
certain other shareholders (the "Sellers") $13,633,500 in cash in consideration
for the Acquired Shares. The Company will pay up to $1,515,350 in cash to the
Sellers one year from the acquisition date subject to certain adjustments and
set off rights under the Plan as described above.
        
         The Company also made a capital contribution of $10,000,000 in cash to
MSI on February 17, 1998 pursuant to the Plan to facilitate MSI's payment of
various creditors pursuant to the Plan. Finally, James S. Johnson and John
Greenwood were paid a total of $300,000 pursuant to consulting and
non-competition agreements executed in connection with the transaction.
        
FINANCING FOR THE ACQUISITION

         The Company financed the acquisition (approximately $25,000,000) 
through expanded interim financing arrangements in the form of a   revolving
line of credit from a commercial bank. DESCRIPTION OF ACQUIRED BUSINESS
        
         Micron Separations, Inc. is a prominent developer, manufacturer, and
marketer of microfilter membrane products for laboratory, diagnostic, and
industrial use. MSI provides a full line of microfiltration (MF) membranes to
complement the Company's existing complete line of ultrafiltration (UF), NF and
RO membranes. This includes nylon membranes 6,6 and 4,6 which are among the most
hydrophilic microfiltration membranes available, and are widely used in food,
beverage and biotech filtration. The acquisition positions the Company as a more
significant player in the laboratory and diagnostics market, while significantly
expanding its capabilities in the pleated membrane cartridge business.

                               (DECEMBER 15, 1997)

         Micron Separations, Inc. ("MSI"), a New York corporation with a usual
place of business in Westborough, Massachusetts, filed a voluntary petition for
reorganization under Chapter 11 of the Bankruptcy Code, 11 U.S.C. ss.101-1330 as

the above-captioned Chapter 11 case. MSI's Chapter 11 case has been pending
before the Honorable James F. Queenan, Jr., United States Bankruptcy Judge, as
case number 97-42342-JFQ. MSI, without interruption, has operated its business

1108 of the Bankruptcy Code since the commencement of its Chapter 11 case.

         This Disclosure Statement is provided pursuant to Section 1125 of the
Bankruptcy Code to all known holders of claims against and interests in MSI (the
"Debtor") whose claims and 

                                       1

interests are impaired under the Debtor's Joint Plan of Reorganization (the
"Joint Plan") and other parties in interest in connection with the solicitation
of acceptance of the Joint Plan. The purpose of this Disclosure Statement is to

     THE DEBTOR RECOMMENDS THAT YOU VOTE TO ACCEPT THE JOINT PLAN.

     IT IS IMPORTANT THAT YOU VOTE. Subject to certain objections, in order to 
obtain confirmation of the Joint Plan by the Bankruptcy Court, the Joint Plan
must be accepted by holders of claims in Class Four WHO ACTUALLY VOTE on the
Joint Plan who hold at least a majority in number and two-thirds in amount, and
Equity Interests in Class Five WHO ACTUALLY VOTE on the Joint Plan who hold at
least two-thirds in amount. In addition, the Bankruptcy Court must make various
findings required by Section 1129 of the Bankruptcy Code, including, among
others, that confirmation of the Joint Plan is not likely to be followed by
liquidation or further financial reorganization. These requirements are more
fully discussed in Section XXVII hereof.

                          I. DESCRIPTION OF THE DEBTOR

     The Debtor is a New York corporation formed in 1981. Initially, its 
marketing and administration were located in Honeyoye Falls, N.Y., but in 1987,
marketing, administration and manufacturing were consolidated in Westborough,
Massachusetts.

     The company was formed to develop, manufacture and market microporous 
membranes and filters for sale to pharmaceutical, food and beverage, electronic,
OEM and research concerns. These membranes and filters, classified as
"microfiltration"

                                       4

<PAGE>   5


products, remove sub-micron sized particles (from 0.05 to 20.0 microns)
suspended in liquids or gases.

     At the time of the filing of the petition, the Debtor was operating its
manufacturing and distribution operations at three adjacent buildings in
Westborough, Massachusetts. Those locations are 125, 131 and 135 Flanders Road.
The company currently has approximately seventy-one employees.

     MSI currently operates out of approximately 50,000 square feet of space, of
which 3,000 square feet are devoted to research, development, and a model shop,
3,000 square feet are devoted to office activities, and the remainder is used
for manufacturing and warehousing.

     MSI is privately held. Approximately 35% of the stock is owned by Edward 
Ackley, John Greenwood and James Johnson, collectively, who were the original
founders.

                          II. HISTORY OF THE BUSINESS

     MSI was founded in 1981 by Edward Ackley, John Greenwood and James 
Johnson.  MSI began its development work on membranes in 1982 and in
that year introduced its first membrane, which was made of a mixture of
nitrocellulose and cellulose acetate polymers. In 1984 MSI introduced its first
nylon microporous membrane made of nylon 66 polymer.

     MSI sells over 2,000 microfiltration products, 97% of which the company 
develops and manufactures in its own facilities, and the remainder manufactured
by others and sold


                                       5

<PAGE>   6


under the MSI private label. The manufacturing of microfiltration products
entails both production of the membrane itself and conversion of this material
into products useable in the marketplace.

     MSI's microfiltration products can be separated into those that serve the
laboratory market (small scale applications) and those that are directed towards
the large scale, high value industrial process filtration market.

     Laboratory products consists of sheets (membranes) cut in rectangular or
circular form with areas from one square centimeter to 1,500 square centimeters.
In addition, MSI produces filtration devices which are largely used by companies
in the medical and health care industries. The devices include syringe filters,
filter funnels, vacuum filter units, monitors and centrifuge filters.

     MSI also produces a wide range of process filtration products. These 
consist of cartridges and capsules. All of these products are available with
various membrane filter types, including: nylon filters, cellulosic filters,
PVDF (polyvinylidene diflouride), PTFE (polytetrafluoroethlylene), polysulfone
and polycarbonate.

     MSI uses distributors to sell to the laboratory market and uses its own 
direct sales force, distributors, and manufacturer's representatives to sell to
the industrial


                                       6

<PAGE>   7


process market; MSI exports approximately 33% of its products worldwide. 

                  III. EVENTS LEADING TO THE CHAPTER 11 FILING

     On May 7, 1986, Pall Corporation (hereinafter "Pall") of Glen Cove, New 
York, filed suit against MSI for infringement of a patent Pall held on a narrow
class of alcohol-insoluble, hydrophilic polyamide membrane filtered media and
product. That case bears docket number 86-1426-WGY (United Stated District Court
for the District of Massachusetts). On June 24, 1991, after a trial on the
merits, the Court entered a judgment and awarded damages to Pall for MSI's
patent infringement through that date. These pre-June 20, 1991 damages totaled
$4,434,291. Both Pall and MSI appealed the judgment. On September 26, 1995, the
U.S. Court of Appeals for the Federal Circuit affirmed the judgment of
infringement, reversed the judgment as to willful infringement, increased the
measure of damages and remanded the case for recalculation of damages. On
November 25, 1995, the Court entered a Separate and Final Judgment of
$12,250,364 together with interest from November 1, 1995 at 8.75%. On December
31, 1995, MSI filed a Petition for Certiorari with the United States Supreme
Court. The Petition was denied on March 17, 1997.

     In the same case, on October 3, 1996, the Court entered a separate and 
final judgment of $4,085,033, together with


                                       7

<PAGE>   8


interest thereon for infringement from September 24, 1991 to September 24, 1996.
MSI sought a stay of execution on the October 3, 1996 judgment, but that was
denied. MSI then sought to appeal the denial of the stay in the United States
Court of Appeals for the Federal Circuit and filed an emergency motion for an
injunction pending the appeal. On April 18, 1997, the emergency motion was
denied.

     Pall obtained an execution on the October 3, 1996 judgment and on April 9, 
1997, sought to execute on the assets of MSI. MSI immediately filed the Chapter
11 proceeding.

                  IV. BRIEF SUMMARY OF ASSETS AND LIABILITIES
             AND OTHER FINANCIAL INFORMATION AT THE TIME OF FILING

     MSI's Bankruptcy Schedules and Statement of Financial Affairs, filed with
the Bankruptcy Court on May 8, 1997, indicated that MSI owed no secured debt and
nearly $12,000,000 of unsecured debt. Pall Corporation accounted for
approximately $10,750,000 of the unsecured debt and the balance was owed to 143
other trade and general unsecured creditors. In its Schedules, MSI included cash
of approximately $2,775,000, trade accounts receivable of approximately
$1,700,000, a tax refund of $1,500,000, various patents worth approximately
$500,000, machinery and equipment worth approximately $275,000 and inventory
worth approximately $750,000.

<PAGE>   9


                      V. STOCK OPTIONS, BONUSES, AND ERISA

     As of the Filing Date there were 127,621 common stock options and warrants,
outstanding and exercisable at various prices. These options and warrants were
issued pursuant to:

          1983 - Employee Options Plan 
          1991 - Option Plan for Directors 
          1991 - Options Granted with Employment Agreements 
          1991 - Incentive Stock Option


     Furthermore, there is an employee incentive stock option plan and an 
employee bonus plan for 1997. The stock option plan for fiscal year 1997
(October 27, 1996 to October 26, 1997) provides for the distribution of stock
options among a pool of 27 employees based on their salaries. The plan is based
on sales growth where a specific amount of shares will be reserved and then
later allocated to eligible employees. The threshold is 15% of growth in sales.
Once the threshold is reached, MSI will reserve 1,000 shares of stock for each
percent of sales growth in excess of last year's sales. For instance, if sales
increase 18% over last fiscal year, then 18,000 shares will be the pool from
which options will be issued.

     The 1997 incentive bonus plan (fiscal year 1997) provides for a bonus 
computed as a percentage of wages earned if total sales grow to certain
thresholds. This plan is available to 25 employees.

15% or greater                                                     5%

     In addition, seven sales personnel would be entitled to this incentive
bonus computed, however, on the percentage increase in their territory.


     The Debtor also has a 401(K) Savings Plan for employees. For fiscal year 
1996 the Debtor matched 50% of the employees' first 5% of earnings and 25% on

                       VIII. REAL PROPERTY AND LEASEHOLDS

         The Debtor does not own and never has owned any interest in any real
property other than a leasehold interest. The Debtor leases three pieces of
non-residential real estate.

<PAGE>   15


         It leases 131 Flanders Road, Westborough, Massachusetts from 129
Flanders Office Associates, L.P. This lease covers 7350 square feet at $4.50 per
square foot. The property is leased until March 31, 1998. The extension option
on this property lapsed on March 31, 1997. There is a prepetition rent arrearage
on 131 Flanders Road in the amount of $6,428.21.

         The Debtor leases 24,400 square feet at 135 Flanders Road, Westborough,
Massachusetts from 129 Flanders Office Associates, L.P. The lease is presently
at $5.40 per square foot which will rise to $5.50 per square foot on May 1,
1998. The lease expires on April 30, 1999, but the Debtor holds an extension
option which must be exercised by April 30, 1998. The rental during any extended
term would be 95% of the fair market rental. There is a prepetition rent
arrearage of $10,821.04 on 135 Flanders Road.

         The Debtor offered to pay the $17,249.25 of combined rent arrearage to
129 Flanders Office Associates, L.P. in return for a reinstatement of the
extension option on 131 Flanders Road to September 22, 1997. This was opposed by
the Committee and Pall Corporation. On September 2, 1997, the Bankruptcy Court
denied Debtor's motion to pay the prepetition indebtedness to 129 Flanders
Office Associates. Although Debtor successfully extended its time to assume or
reject the 

                                       15

leases, it does not hold an option to renew its lease on 131 Flanders
Road, Westborough, Massachusetts.

         The Debtor also leases units 13, 15, and 16 at 125 Flanders Road,
Westborough, Massachusetts from 125 Flanders Associates. This lease covers
approximately 15,000 square feet and the lease expires on January 31, 1999. The
present lease is $7,812.50 per month or approximately $6.25 per square foot.
Debtor has the right to renew this lease for an additional period of three (3)
years by notice by July 31, 1998. The new lease rate for the additional period
would be at market. 

                  IX. OPERATION OF BUSINESS DURING CHAPTER 11

         During Chapter 11, the Debtor's sales have continued to increase, and
the Debtor has been profitable despite extraordinary legal expenses. KPMG has
prepared the following income statement for the Chapter 11 period:

 (1)  all Corporation v. Micron Separations, Inc., Civil Action No. 86-1427-WGY.

Complaint. Pall commenced this patent infringement action against MSI on May 7,
1986. Pall sought a judgment that MSI willfully infringed its patent covering
the process for preparing hydrophilic polyamide membrane filtered media and
product. Pall also sought damages for past infringement as well as an injunction
against future infringement.

Initial Judgment. On June 24, 1991, after trial on the merits, the United States
District Court for the District of Massachusetts ("the District Court") entered
a judgment and awarded damages to Pall for MSI's patent infringement through
that date. These pre-June 20, 1991 damages, including lost profits, royalty
damages, willfulness damages and interest and attorneys' fees, totaled
$4,434,291 (the "Initial Judgment"). The District Court entered a stay of the
judgment as it related to nylon 46. Both Pall and MSI appealed the judgment.

MSI's First Chapter 11. In order to avoid execution upon the Initial Judgment,
MSI filed a voluntary petition under Chapter 11 on July 22, 1991. On December
18, 1991, Pall and MSI entered into an agreement which provided that during the
pending appeal of the Initial Judgment MSI would escrow certain monies and Pall,
subject to certain terms and conditions, would forbear from executing on a
judgment so long as MSI complied with the provisions of the agreement. The
agreement was approved by the Bankruptcy Court and, as part of the Agreement,
MSI dismissed its Chapter 11 case. The case was dismissed and closed on 
December 30, 1991.



                                       18

<PAGE>   19

Appellate Review of Initial Judgment. On September 26, 1995, the United States
Court of Appeals for the Federal Circuit affirmed the judgment of infringement,
reversed the judgment as to willful infringement, increased the measure of
damages and remanded the case for recalculation of damages, and vacated the stay
of the injunction as to nylon 46 membrane.

$12 Million Judgment. On November 24, 1995, in accordance with the decision of
the United States Court of Appeals, the District Court entered a Separate and
Final Judgment of $12,250,364, together with interest from November 1, 1995
through date of Judgment of 8.75% per annum, post judgment interest at the prime
rate of interest as promulgated by Citibank, N.A., and reiterated the injunction
against MSI and those in concert with MSI from infringing upon Pall's patent by
virtue of the sale, use, or manufacture of nylon 46 or nylon 66.

Certiorari Denied. On December 31, 1995, MSI filed a Petition for Certiorari
with the United States Supreme Court seeking review of the United States Court
of Appeals decision. The Petition was denied on March 17, 1997.

                                       19

<PAGE>   20


$4 Million Judgment. On October 3, 1996, the District Court entered a separate
and final judgment of $4,085,033 for infringement from June 24, 1991 to June 24,
1996, together with interest thereon from September 24, 1996 through the date of
judgment at $923 per day and post-judgment interest at the statutory rate
specified in 28 U.S.C. ss.1961.

Appeal from $4 Million Judgment. MSI filed an appeal in the United States Court
of Appeals for the Federal Circuit (Appeal 97-1141) from the $4 Million Judgment
on the grounds that the form of judgment was incorrect: that the judgment should
not be a separate judgment but should be a modification of the November 24, 1995
judgment. The matter is fully briefed and the Bankruptcy Court has lifted the
stay. MSI sought a stay of execution and in connection therewith, claimed that
the $4 million Judgment was subject to the December 18, 1991 agreement between
Pall and MSI. On April 3, 1997, the District Court ruled that the "agreement
between the parties had no effect on the judgment of this Court." Following the
ruling, MSI sought an emergency stay of execution, which was denied. Immediately
prior to the commencement of its second chapter 11 proceeding, MSI filed a
further appeal from the denial of the stay to the United States Court of Appeals
for the Federal Circuit (Appeal 97-1298) and an emergency motion for an
injunction pending 

                                       20
<PAGE>   21


appeal. On April 18, 1997, the emergency motion was denied. The Bankruptcy Court
has lifted the stay nunc pro tunc to April 9, 1997. Appeal 97-1298 has been
dismissed.

(2) Micron Separations, Inc. v. Pall Corporation, Civil Action No. 94-11377-WGY.

Complaint. MSI commenced this declaratory judgment action against Pall on July
8, 1994 seeking a declaration of patent non-infringement and the invalidity of
Pall's patent. The Complaint seeks damages as well as injunctive relief. Pall
answered the Complaint on July 12, 1994 denying the allegations therein. On July
12, 1994, the District Court issued a preliminary injunction against MSI and
those acting in concert with it enjoining the manufacture, use and sale of
membrane products made of type 8 nylon. Pall also filed a Counterclaim against
MSI alleging patent infringement by MSI subsequent to the decision in Pall
Corporation v. Micron Separations, Inc., Civil Action No. 86-1427-WGY. MSI
responded to the Counterclaim on September 8, 1994 by denying the allegations
therein.

Procedural History. On September 2, 1994, Pall moved for Partial Summary
Judgment on issue preclusion. MSI opposed the Motion on September 20, 1994 and
also filed a Motion for 

                                       21

<PAGE>   22


Summary Judgment of non-infringement and issue preclusion. Pall opposed MSI's
Motion on October 6, 1994, and also filed a Cross-Motion for Summary Judgment.
On November 16, 1994, the Court allowed in part and denied in part Pall's Motion
for Partial Summary Judgment.

Bench Trial. A bench trial commenced on January 26, 1995, and continued on
January 27, 30, 31, February 1, 2, 3, 6, 7, 8, 13, 14 and 15, 1995.

(3) Pall Corporation v. Micron Separations, Inc., District Court, Civil Action
No. 95-12731-WGY.

Complaint. Pall commenced this patent infringement action against MSI on
December 18, 1995. Pall seeks damages for MSI's continuing infringement of its
patent covering the process for preparing hydrophilic polyamide filter media and
product as well as an injunction against future infringement. MSI answered the
Complaint by denying the allegations therein.

Consolidation.  This action was consolidated by Judge Young with C.A. No.
95-12473.

(4) Pall Corporation v. Fisher Scientific Company, Inc., District Court, Civil
Action No. 95-12473-WGY.

Complaint. On November 13, 1995, Pall commenced this action against Fisher
Scientific Company, Inc. ("Fisher") alleging that Fisher, as an agent for MSI
and/or as an independent distributor, sold nylon 46 membrane made by MSI after
the Court of Appeals vacated the stay of the injunction. Pall is seeking damages
for past infringement as well as injunctive relief. Fisher answered the
Complaint and denied the allegations therein. Fisher also filed a Counterclaim
against Pall seeking damages for breach of contract and filed a Third-Party
Complaint against MSI for indemnification. MSI has answered the Third-Party
Complaint and denied the allegations therein. MSI also filed a Third-Party
Complaint against Pall alleging that Pall is in violation of the December 18,
1991 Agreement. MSI amended its Answer and Third-Party Complaint on February 6,
1996 adding claims against Pall for unfair competition and commercial
disparagement in violation of the Lanham Act and tortious interference with
advantageous business relationships.

Consolidated and Amended Complaint. On July 2, 1996, Pall filed an Amended
Complaint in the consolidated action 

                                       23

<PAGE>   24

including claims against both Fisher and MSI. The Amended Complaint includes
claims against Fisher for patent infringement, tortious interference with
contractual relations and violation of injunction, and claims against MSI for
patent infringement, breach of contract and violation of injunction. In
addition, the Amended Complaint includes a charge of civil conspiracy by and
between Fisher and MSI.

Administrative Closure. By order of the District Court, and in accordance with
the Settlement Agreement (defined below), this case was administratively closed,
subject to reopening in the event that: (a) the Settlement Agreement is not
approved by the Bankruptcy Court; (b) the Joint Plan is not confirmed; or (c)
Pall is not paid in accordance with the Settlement Agreement.

         (5) Micron Separations, Inc. v. Pall Corporation, U.S. Bankruptcy Court
for the District of Massachusetts, Adversary Proceeding No. 97-4161-JFQ. On
April 17, 1997, the Debtor commenced an adversary proceeding against Pall
Corporation seeking a Declaration of Debtor's payment obligations to Pall under
their December 18, 1991 Agreement ("1991 Agreement"). The 1991 Agreement
obligated Debtor to pay Pall two-thirds of Debtor's net after-tax profits,

                                       24
<PAGE>   25


subject to certain adjustments, all as determined by KPMG Peat Marwick. Debtor
contended that the November 24, 1995 judgment in the amount of $12,250,364.00
(the "1995 Judgment") and the other dated October 3, 1996 in the sum of
$4,085,033.00 (the "1996 Judgment") were covered by the 1991 Agreement and, so
long as the Debtor complied with the Agreement, Pall could not execute on those
judgments against the Debtor. The Bankruptcy Court tried the case on September
22 and September 23, 1997. On September 30, 1997, Judge Queenan issued the
Court's Judgment, stating, among other things, that Debtor had not breached the
1991 Agreement and that the 1991 Agreement governs MSI's payment obligations
under the 1995 and 1996 Judgments. The Court further found that Debtor is
entitled to a credit of $3,726,429.00 on its payment obligations to Pall.
Finally, the Court enjoined Pall from taking any action to collect on the 1996
or 1995 Judgments. The September 30, 1997 Judgment was entered contingent upon
MSI's assumption of the 1991 Agreement pursuant to Court approval.

         (6) Settlement. Subsequent to the September 30, 1997 decision by the
Bankruptcy Court, Pall and MSI negotiated a settlement of all of the outstanding
litigation and issues between the parties. On November 20, 1997 (effective as of
November 18, 1997), MSI and Pall entered into a Settlement Agreement
("Settlement Agreement") which provides, among 

                                       25
<PAGE>   26


other things, that upon Pall's receipt of $13.5 million, it will:

         a) Dismiss all pending litigation against MSI and Fisher Scientific 
         Company (86-1427-WGY; 94-11377-WGY; 95-12731-WGY; 95-12473-WGY)

         b) Release MSI and its customers from any alleged patent infringements
         occurring prior to approval of the Settlement Agreement with regard to
         Pall's Patents No. 4,340,479; 4,340,480; and 5,543,047; and

         c) Agree not to sue Osmonics, MSI, or MSI's customers for alleged
         infringement of patents 4,340,479 and 4,340,480 through the remaining
         term of those patents; and for a one year period from the date of
         confirmation, not to sue MSI, MSI's customers, or Osmonics on any
         alleged infringement of Patent No. 5,543,047.

         MSI will:

         a) Release Pall;

         b) Dismiss all pending litigation against Pall (94-11377-WGY;  
         95-12473-WGY;  97-4161-JFQ);  and

         c) Agree that one year after confirmation, it will have a limited
         inventory with respect to goods similar to MSI's glass over nylon clayx
         cartridges if it wishes to be covered by Pall's agreement not to sue
         with regard to those products.

         That Settlement Agreement has been presented to the Bankruptcy Court 
for its approval and is attached to the Joint Plan as an exhibit. The
description of the Settlement Agreement is summary only and is qualified by
reference to the actual terms and conditions of the Settlement Agreement itself.

                   XI. SUMMARY OF THE PROVISIONS OF THE PLAN

         A summary of the principal provisions of the Joint Plan is set forth
below. All defined terms used in this Section have the meaning assigned to such
terms in Article I of the Plan unless otherwise defined herein. THIS DESCRIPTION
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE PLAN WHICH IS ATTACHED AS
EXHIBIT A, WHICH EXHIBIT SHOULD BE REFERRED TO FOR A FULL AND COMPLETE
DESCRIPTION OF THE RELEVANT PROVISIONS.

         By way of summary, the Joint Plan provides for the cancellation of all
existing equity interests of the Debtor and the issuance of capital stock to
Osmonics, Inc. in consideration of Osmonics paying $28 million. Funding for the
monies distributed under the Joint Plan shall be provided from the acquisition
funds to be deposited by Osmonics and up to $3,200,000 of the cash held by the
Debtor at the Effective Date. Cash on hand up to $3,200,000 on the Effective
Date and the said $28 million will be used to pay all Allowed Administrative
Claims, tax claims, and all Class Three and Four unsecured claims, which,
pursuant to the Joint Plan, will be paid in full; Class Three claims will
receive interest at 8 1/2% per annum from April 9, 1997 to the date of payment;
Class 4 Claims will be paid in accordance with the Settlement Agreement; and
shareholders will receive approximately $15.2 million in satisfaction of their
claims and interests. 


                                       27

<PAGE>   28


Shareholders will, on the Effective Date, receive $13,680,000, but from that
amount, $100,000 will be set aside to pay expenses in the Kenyon & Kenyon
litigation, $317,025 will go to the Disputed Claims Reserve for the Kenyon &
Kenyon claim, and $60,000 will go to the Disputed Claims Reserve to pay interest
on the Kenyon & Kenyon claim, if it is ever allowed. Thus, only $13,213,000 will
be distributed to shareholders. Ten (10%) percent of the shareholders'
distribution (approximately $1,520,000) will be held back and will be subject to
certain representations and warranties of the Debtor contained in Exhibit B to
the Plan. As part of their employment contracts, Osmonics will pay James Johnson
$200,000 and John Greenwood $100,000, which payment does not come from the
Funded Amount or the Debtor's cash.

           The Plan and Settlement Agreement end all of the outstanding
litigation between MSI and Pall Corporation.

                      XII. POST-PETITION PAYMENTS MADE TO

                          UNSECURED PRIORITY CREDITORS

         On April 9, 1997, the Debtor filed a motion requesting the Court to
enter an order permitting the Debtor to pay certain wage claims of its hourly
and salaried employees and certain commissions of its salesmen, totaling
$69,760. All such claims were due to employees for wages, vacation and
commissions, none of which were incurred more than sixty (60) 

                                       28

<PAGE>   29


days prior to the Chapter 11 filing. The Debtor believes that all such payments
were entitled to priority pursuant to ss.507 of the Bankruptcy Code. No
individual employee was paid more than the statutory maximum of $4,000 per
employee. The request to pay these pre-petition claims was made on an emergency
basis after the Debtor gave notice to the twenty (20) largest creditors of the
estate, the U.S. Trustee and any other party who had filed an appearance and
request to receive pleadings filed with the Bankruptcy Court.

         On August 7, 1997, the Debtor filed a motion requesting the Court to
enter an order permitting the Debtor to pay its landlord at 131 and 135 Flanders
Road in Westborough, Massachusetts, $17,249.25 in pre-petition rent. The Debtor
believed that it would seek to assume its real estate leases and payment of all
pre-petition arrearages if necessary in order to assume such leases, the
proposed plan will provide for a 100% dividend, and the landlord agreed to
extend the option (which had expired pre-petition) to renew the lease until
September 22, 1997, in exchange for the payment. The Creditors' Committee and
Pall Corporation opposed the drop dead date. On September 2, 1997, after
hearing, Judge Queenan denied the Debtor's motion to pay the landlord hearing
$17,249.25 in pre-petition rent.

                        XV. CLASSIFICATION AND TREATMENT
                             OF CLAIMS AND INTERESTS

         The Joint Plan divides all existing claims and interests into the
  classes as indicated in the following paragraphs. Although each class is
  defined generally, specific reference to the Joint Plan should be made to
  understand the classification of your claim:

         (i.) Class One -- Administrative and Priority Claims

         Administrative Claims are all claims for goods and services incurred by
  the Debtor subsequent to the filing of its Chapter 11 petition on 4/9/97.
  These claims (other than for professional services by attorneys, accountants
  and other professionals, and such other administrative expense claims that
  require Bankruptcy Court approval) shall be paid in full in accordance with
  their terms as they come due in the ordinary course of the continuation of the
  Debtor's business after the Effective Date. If any dispute should arise
  concerning any claim for such expenses, such dispute shall be resolved by the
  Bankruptcy Court and the Allowed Claim paid as provided below.

                                       35

<PAGE>   36



         Administrative Claims for professional services, i.e., those of
  attorneys or accountants, require Bankruptcy Court approval. Those claims will
  be paid, in full, only after entry of orders by the court allowing these
  claims in full or in part after notice and hearing. The estimated final fee
  requests for such professionals are as follows:

                        Estimated Final Fees and Expenses
                          (including amounts previously
                              approved and/or paid)

</TABLE>

         Jager, Smith & Stetler, as bankruptcy counsel to the Debtor, received a
  retainer at the inception of the Debtor's chapter 11 case in the amount of
  $95,012.00. The 

         (2) This claim may not require Bankruptcy Court approval.  The Goodwin,
Proctor bill involves $246,000 pre-petition, $240,000 post-petition, and
$121,000 of post-petition expert expenses.

Debtor also has paid Creditors' Committee counsel a $25,000 retainer, pursuant  
to Orders entered by the Court. Testa, Hurwitz & Thibeault had a retainer from
the Debtor in the amount of $50,000, and the Law Offices of Bruce Jacobs had a
retainer from the Debtor in the amount of $30,000.

         Priority Claims are those claims which are entitled to priority,
pursuant to Section 507(a) of the Bankruptcy Code. They include certain claims
for wages (including vacation, severance and sick leave pay under Section
507(a)(3) and Section 507(a)(4)). Taxes, which are also a priority under
Section 507(a)(8), are separately classified in Class Two. Upon the
commencement of the Debtor's Chapter 11 case, the Debtor listed no such
claims. To the extent that any priority claims are subsequently filed, the
holders shall be paid in full within ten (10) days of the Effective Date or,
if disputed, when allowed by the Bankruptcy Court, whichever is later.

         (ii.)  Class Two -- Tax Claims
  
       Tax claims are entitled to priority under Section 507(a)(8) of the
Bankruptcy Code. Upon the commencement of the Debtor's chapter 11 case, the
Debtor listed no such claims. The Commonwealth of Massachusetts Department of
Revenue has filed a Proof of Claim in the amount of 

                                       37

<PAGE>   38


  $31,124.00. The Internal Revenue Service has filed a proof of claim for 
  $327,222.34 for income tax liability for the year ending October 30, 1995. 
  This amount was set-off against a refund of $1,292,935.00. The net amount was 
  refunded to the Debtor. In addition, the Debtor owes the United States 
  Internal Revenue Service at least $14,216.31 in interest on its 1993 and 1994 
  1120DF. Such tax priority claims will be paid in full within (10) days of the 
  Effective Date or, if disputed, when allowed by the Bankruptcy Court, 
  whichever is later.

         (iii)  Class Three - General Unsecured Creditors'
  
                  Claims

         Class Three consists of all general unsecured claims, except those of
  Pall Corporation, but including any persons or entities asserting damages by
  reason of the Debtor's rejection of any executory contract or unexpired lease
  under the terms of the Joint Plan or any motion hereafter filed by the Debtor.
  The Debtor's Schedules list aggregate undisputed Class Three claims in the
  amount of $667,584.60. The Bankruptcy Court set August 11, 1997, as the last
  day for filing Proofs of Claim in this case (other than claims resulting from
  the subsequent rejection of executory contracts or unexpired leases.) The
  Proofs of Claim, as filed, increased undisputed Class Three claims (without

                                       38

<PAGE>   39


  regard to the Pall Claims) by $140,240.32. The landlord, 129 Flanders
  Associates, did file a $311,249.44 Proof of Claim, which would only have
  validity if the leases were rejected. The Debtor is not rejecting the leases.
  The undisputed claims now total $807,824.92. The Debtor does not presently
  intend to object to any proofs of claim other than the 129 Flanders and Kenyon
  & Kenyon claims. The disputed claims of 129 Flanders and Kenyon & Kenyon bring
  the total Class 3 claims to $1,436,099.30.

         Holders of Class Three Claims shall be paid in full with interest at
  the rate of 8 1/2% per annum within ten (10) days of the Effective Date or, if
  disputed, when allowed by the Bankruptcy Court, whichever is later. Interest
  will be paid for the period from April 9, 1997 to payment.

         (iv)  Class Four - Claims of Pall Corporation

         Pall Corporation and the Debtor have entered into a Settlement
  Agreement dated November 18, 1997, which has been approved by the Bankruptcy
  Court on December 15, 1997. The Settlement Agreement provides for a
  $13,500,000 payment to Pall. The Settlement is more fully discussed in Article
  X.

        (v)  Class Five - Common Stock


                                       39

<PAGE>   40


         Under the Joint Plan, holders of Equity Interests in the Debtor as of
  the Confirmation Date will receive a pro rata share of $13,213,000 within ten
  (10) days after the Effective Date. The Equity Interests Trustee will have set
  aside $100,000 for the costs and expenses of the Kenyon & Kenyon litigation
  and paid to the Disputed Claims Reserve $317,025 for the Kenyon & Kenyon claim
  and $60,000 for interest thereon. This amount is subject to dilution if the
  amount of administrative claims or unsecured claims exceeds the amounts
  presently anticipated. Holders of Equity Interests shall, on the first
  anniversary of the Effective Date, receive a pro rata share of $1,520,000,
  less any permitted setoffs above the amount of $100,000. The Debtor has made a
  series of representations and warranties concerning its assets, financial
  condition and status. If there is a material variance from these
  representations and warranties which reduces the value of Debtor to Osmonics,
  then Osmonics has a right of set off against the 10% held back for
  shareholders. Those representations and warranties are contained in Exhibit B
  to the Plan on file with the Court and are also available, upon request from
  Bruce F. Smith, Counsel to the Debtor at the following address:

or from Larry A. Koch, Esq., Counsel to Osmonics at the following address:


                  Maslon, Edelman, Borman & Brand
                  3300 Norwest Center
                  Minneapolis, MN 55402,

         Shareholders will also receive a pro rata share of the malpractice
  claim the debtor is presently prosecuting against Kenyon & Kenyon. Kenyon &
  Kenyon is the law firm which initially represented the Debtor in its patent
  litigation with Pall. That action is pending in Worcester (Massachusetts)
  Superior Court under Docket No. 94-0504. Osmonics will fund $100,000 towards
  fees and expenses of that litigation and Shareholders will fund $100,000 from
  the Equity Consideration towards fees and expenses in that litigation.

                          XVI. RIGHTS OF SHAREHOLDERS

         All shares of stock and options and warrants to purchase shares of
  stock in MSI will be canceled at Confirmation. New shares of stock in MSI will
  be issued to Osmonics.

                     XVII. PROPOSED DIRECTORS AND OFFICERS
                         AND THEIR EXPECTED COMPENSATION

                  D. Dean Spatz             Director

                  L. Lee Runzheimer         Director

                  James S. Johnson          Director

                  D. Dean Spatz             Chief Executive Officer

                  James S. Johnson          Chief Operating Officer and
                                            President

                  L. Lee Runzheimer         Treasurer

                  Ruth Carol Spatz          Secretary

         Neither Mr. Spatz nor Mr. Runzheimer will not receive any compensation 
from the reorganized Debtor. Mr. Johnson's compensation will be $192,000/annum.

                    XVIII. PREFERENCES, FRAUDULENT TRANSFERS
                           AND OTHER CAUSES OF ACTION

         After examining the books and records, the Debtor has been unable to
  identify any claims concerning preferences pursuant to Section 547 of the
  Bankruptcy Code. Similarly, the Debtor has been unable to identify any
  fraudulent transfer claims pursuant to Sections 544 and 548 of the Bankruptcy
  Code. To the extent, however, that such claims exist, they are irrelevant in
  light of the 100% distribution to creditors.


                                       42

<PAGE>   43



                       XIX. TAX CONSEQUENCES TO CREDITORS

         A creditor who receives cash or property in satisfaction of its Allowed
  Claim will recognize ordinary income to the extent that the amount received is
  allocable to interest that accrued while the claim was in its hands. In
  addition, such creditor will recognize gain or loss on the exchange equal to
  the difference between the creditor's basis in the Allowed Claim and the
  amount of consideration received that is not allocable to interest. The
  character of any recognized gain or loss will depend upon the status of the
  creditor, the nature of the claim in its hands and its holding period.

                   XX. MEANS FOR EXECUTION OF THE JOINT PLAN

         1. Revesting of property of the estate. On the Confirmation Date,
  reorganized MSI shall be revested with the property that was formerly the
  property of the estate (including any claims belonging to the Debtor or the
  estate) and reorganized MSI will continue its business in the ordinary course
  as it existed prior to the Petition Date. Except as specifically provided
  herein the property of reorganized MSI will be free and clear of all claims,
  interest, liens, and encumbrances. The Kenyon & Kenyon malpractice and breach
  of contract action will vest in the Equity Interests Trustee.

                                       43

<PAGE>   44



         2. Distributions. The Disbursing Agent (Debtor's Counsel) will make the
  distributions under the Joint Plan to Classes 1-4. The Equity Interests Trust
  will distribute the Equity Consideration to Class 5. There shall be paid to
  the holder of any option or warrant a distribution in the same proportion as
  if such option holder were a shareholder on the Confirmation Date. The option
  holder shall pay the exercise price separately to the reorganized Debtor. The
  Equity Consideration will be paid to the Equity Interests Trust with its own
  trustee. That Equity Interests Trustee will have the power and authority to
  contest any asserted hold backs by Osmonics. That Equity Interests Trust will
  make the distributions of the hold back amounts at the appropriate time for
  distribution. The Equity Interests Trust will hold the cause of action and
  direct the malpractice and breach of contract litigation between MSI and
  Kenyon & Kenyon and will distribute the proceeds, when and if recovered.

         3.  Reserve for Disputed Claims.

         A. On the Effective Date, the distributions reserved for the holders of
  disputed claims shall be delivered to the Disbursing Agent (Debtor's Counsel)
  but shall be held 

                                       44

<PAGE>   45


in a segregated, interest-bearing account (the "Disputed Claims Reserve") for
the benefit of holders of disputed claims entitled thereto under the Joint Plan.
There will be deposited into the Disputed Claims Reserve an amount of cash which
would have been distributed on account of the disputed claims if all disputed
claims were allowed in the full amount claimed by the holders thereof with
interest.

         At the same time as a Disputed Claim becomes an Allowed Claim, the]
distribution which would have been disbursed had the Disputed Claim been an
Allowed Claim on the Effective Date shall be released from the Disputed Claims
Reserve and delivered to the holder of such Allowed Claim with ten (10) days.

                        XXI. FULL AND FINAL SATISFACTION

         Except as otherwise provided in Section 1141 of the Bankruptcy Code or
in the Joint Plan, including by reference, the Settlement Agreement, the
payments and distributions made pursuant to the Plan will be in full and final
satisfaction, settlement, release and discharge, as against the Debtor, of any
and all claims against, and interests in, the Debtor, as defined in the
Bankruptcy Code, including, without limitation, any claim or equity interest
accrued or incurred on or before the Confirmation 

                                       45

<PAGE>   46


Date, whether or not (i) a Proof of Claim or Interest is filed or deemed filed
under Section 501 of the Bankruptcy Code, (ii) such claim or equity interest is
allowed under Section 501 of the Bankruptcy Code, or (iii) the holder of such
claim or equity interest has accepted the Plan.

                          XXII. EFFECT OF CONFIRMATION

         Except as otherwise provided in the Joint Plan, including by reference,
the Settlement Agreement, all creditors and Equity Interest Holders shall be
precluded after the Confirmation Date from asserting against the Debtor or the
reorganized Debtor, or any of its assets or properties, any other or further
claims or interests based upon any act or omission, transaction or other
activity of any kind or nature that occurred prior to the Confirmation Date, the
Confirmation Order being deemed to permanently enjoin such creditors and
interest holders, their successors and assigns, from enforcing or seeking to
enforce any such claims or interests.

         The Confirmation Order shall provide that, on the Effective Date, the
duties, obligations, and responsibilities of the Creditors' Committee, their
agents, their representatives and counsel shall come to an end, and the
Committee and its counsel, shall be discharged from 

                                       46

<PAGE>   47


their duties, obligations, and responsibilities herein, and the Committee shall
cease to exist.

         To the extent permitted by applicable law, its counsel may seek
compensation and reimbursement of expenses. Members of the Committee may seek
reimbursement of their actual, reasonable and necessary expenses.

                XXIII. EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         Pursuant to the Joint Plan, the Debtor in Possession will file a list
of executory contracts and unexpired leases to be assumed and assigned under the
Joint Plan at least ten (10) days prior to the hearing on confirmation of the
Joint Plan with "cure" payments, if any, to be made by Debtor. Each other
executory contract or unexpired lease that either (i) has expired by its own
terms prior to the Effective Date and was not rejected during the chapter 11
case, or (ii) has not expired by its own terms prior to the effective date, was
not rejected during the chapter 11 case, and is not subject to a pending motion
to assume as of the Effective Date or does not appear in the above-referenced
list of executory contracts and unexpired leases to be assumed will be deemed
rejected as of the Effective Date. The 1991 Agreement will be rejected on the
Effective Date. Any claim for damages arising from the rejection of 

                                       47

<PAGE>   48


any executory contract or unexpired lease not rejected prior to Confirmation
must be filed with the Bankruptcy Court within twenty (20) days following the
Effective Date or be forever barred from receiving any distribution of the Plan.
Debtor will have 30 days from date of filing of claim to file any objection. Any
such claim for rejection, as and to the extent allowed by final order of the
Bankruptcy Court, will be a Class Three claim under the Plan.

                        XXIV. CONFIRMATION REQUIREMENTS

         In order for the Joint Plan to be confirmed, the Bankruptcy Code
requires, among other things, that the Joint Plan be proposed in good faith,
that the Debtor disclose specified information concerning payments made or
promised to insiders, and that the Joint Plan comply with the applicable
provisions of chapter 11 of the Bankruptcy Code. Section 1129(a) of the
Bankruptcy Code also requires that at least one class of claims has accepted the
Joint Plan, that confirmation of the Joint Plan is not likely to be followed by
the need for further financial reorganization, and that the Joint Plan be fair
and equitable with respect to each class of claims or equity interest which is
impaired under the Joint Plan. The Bankruptcy Court can confirm the Joint Plan
if it finds 
                                       48

<PAGE>   49


that all of the requirements of 1129(a) of the Bankruptcy Code have been met.
Even if a plan is rejected by a class, the plan may still be confirmed under the
"cram-down" provisions of Section 1129(b), discussed in Article XXVII.

              THE DEBTOR BELIEVES THAT THE JOINT PLAN SATISFIES ALL
OF THE REQUIREMENTS FOR CONFIRMATION.

                     XXV. BEST INTERESTS OF CREDITORS TEST


         Under the best-interest test, the Plan is confirmable if, with respect
to each impaired Class of Claims or Interests, each holder of an Allowed Claim
or an Allowed Interest in such Class has either (i) accepted the Plan or (ii)
receives or retains under the Plan, on account of its Claim or Interest,
property of a value, as of the Effective Date, that is not less than the amount
such holder would receive or retain if the Debtor were to be liquidated under
Chapter 7 of the Bankruptcy Code.

         To determine what the holders of each class of claims or interest would
receive if the Debtor were to be liquidated, the Bankruptcy Court must determine
the dollar amount that would be generated from the liquidation of the Debtor's
assets in a Chapter 7 liquidation case. The amount that would be available for
satisfaction of the 

                                       49

<PAGE>   50


Allowed Claims and Allowed Interests of the Debtor would consist of the proceeds
resulting from the disposition of the assets of the Debtor augmented by the cash
held by the Debtor at the time of the commencement of the Chapter 7 case. Such
amounts would be reduced by the costs and expenses of the liquidation and by
such additional Administrative Priority Claims and Other Priority Claims that
might result from the termination of the Debtor's business and the Chapter 7
case.

         The costs of liquidation under Chapter 7 would include the fees payable
to the Trustee appointed in the Chapter 7 case as well as those that might be
payable to other professional persons employed by the Trustee. Priority Claims
in the liquidation case would also include any unpaid expenses incurred by the
Debtor in the Chapter 11 case, such as compensation for attorneys, financial
advisors, and accountants, as well as costs and expenses of members of the
Committee appointed in the Chapter 11 case. In addition, Priority Claims may
arise by reason of the breach or rejection of obligations incurred in Executory
Contracts entered into by the Debtor during the pendency of the Chapter 11 case.


                                       50

<PAGE>   51


         To determine if the plan that is proposed is in the best interest of
creditors and interest holders, the present value of the distributions likely to
be made to each class in a liquidating case are compared with the present value
of the distribution to such impaired class provided for by the Plan. Exhibit "A"
attached to this Disclosure Statement provides a detailed analysis of the most
likely outcome of an orderly liquidation of the Debtor conducted by a Chapter 7
trustee and the net distribution after payment of expenses to each class. It
concludes that in a liquidation creditors could expect a return in the 32-45%
range. Equity interests would receive nothing.

         In applying the best-interest test, it is possible that claims in a
Chapter 7 case may not be classified in the same manner as provided for by the
Plan. Priority and orders of distribution of estate assets are established by
the applicable provisions of Chapter 7. Under those provisions, each class of
claims is paid in a descending order of priority. No junior classes of claims
are paid until all senior classes have received payment in full. In the event
that available assets are insufficient to pay all members of such class in full,
then each member of that class shares on a pro rata basis. The Debtor believes
that in the event of liquidation under the auspices of a chapter 

                                       51

<PAGE>   52


7 Trustee, Priority Claims would be paid, some portion of the unsecured claims
would be paid, and existing equity interests would receive no distribution with
respect to their interest. In contrast, under the Joint Plan, all Priority
Claims would be paid the full amount of their Allowed Claims, General Unsecured
Claims will be paid the full amount of their Allowed Claims, and Holders of
Equity Interests will be paid approximately $15.2 million, less any potential
setoffs, dilution due to any larger claims of creditors, the amount necessary to
satisfy the Kenyon & Kenyon claim and the amount necessary to fund the Kenyon &
Kenyon claim.

         THUS, THE DEBTOR BELIEVES THAT THE JOINT PLAN IS IN THE BEST INTEREST
OF ALL CLAIM HOLDERS.

XXVI. FEASIBILITY OF THE PLAN

         Bankruptcy law provides that a plan may be confirmed only if the
Bankruptcy Court finds that it will not lead to the need for further
reorganization or liquidation. In other words, the Plan must be feasible. Since
the Plan provides for MSI to continue in business, the Court must be satisfied
that MSI will not only be able to make the payments due on the Effective Date of
the Plan, but will also be able to meet its obligations thereafter, whether

                                       52

<PAGE>   53


arising under the Plan or incurred under the operation of MSI's business. Since
all the creditors will be paid in full on the Effective Date or when a Final
Order is entered by the Court, there is no issue of feasibility.

                 XXVII. ACCEPTANCE AND CONFIRMATION OF THE PLAN

         Bankruptcy law provides for a plan of reorganization to group various
claims and stock interests into classes, each consisting of parties having
similar legal rights in relationship to the Debtor. Each class may then be
treated as either "impaired" or "unimpaired" under a plan of reorganization.
There are three (3) ways in which a plan may leave a claim or interest
"unimpaired": first, the plan may not propose to alter the legal, equitable or
contractual rights of the holder of the claim or interest; second, all defaults
may be cured and the original terms of the obligation reinstated; third, a plan
of reorganization may provide for payment in full of the obligation to the
holder of the claim or interest. If a class is unimpaired, it is presumed to
vote in favor of the Plan.

         An impaired class that would receive nothing under a proposed plan is
presumed to have rejected the plan. An impaired class that is proposed to
receive any distribution (whether in cash, securities, or other property) has
the 

                                       53

<PAGE>   54


right to vote, as a class, to accept or reject the plan. A class of creditors
accepts the plan if more than one-half (1/2) of the ballots that are timely
received from members of the class representing at least two-thirds (2/3) of the
dollar amount of the claims for which ballots are timely received, vote in favor
of the plan. A plan under which any class of claims is impaired may be confirmed
by the Court only if it has been accepted by at least one such class.

         A plan that is rejected by any class may be confirmed under the
"cram-down" provisions of the bankruptcy law if the Court finds that the plan is
fair and equitable to, and does not discriminate unfairly against, the rejecting
class. In general terms, a plan is fair and equitable to a class if (i)
unsecured claims are either paid in full or no junior class (such as any class
of stockholders) will retain anything under the plan; (ii) preferred
stockholders if a liquidation preference will be paid in full or if no junior
class will retain anything under the plan; (3) common stockholders if they are
paid the full value of their stock (if any). In this context, payment in full
means either immediate payment or else payments over time having a present value
equivalent to immediate payment.


                                       54

<PAGE>   55



         The Plan divides creditor claims and equity holder interests into five
classes. Classes One and Two are unimpaired and thus deemed to accept the Plan.
Classes Three, Four, and Five are impaired and may vote to accept or reject the
Plan.

         The Debtor and Osmonics believe that the Plan meets all the
prerequisites of confirmation.

                            XXVIII. MANNER OF VOTING

         All persons entitled to vote on a plan may cast their vote for or
against such Plan by completing, dating, and signing the Ballot for Accepting or
Rejecting Plan (the "Ballot") accompanying this Disclosure Statement and
returning it in the enclosed envelope addressed to:

         Bruce F. Smith, Esq.
         Jager, Smith & Stetler
         One Financial Center
         Boston, MA 02111
         (617)951-0500

         IN ORDER TO BE COUNTED, ALL BALLOTS MUST BE RECEIVED AND FILED WITH THE
COURT AT OR BEFORE 4:00 PM (EASTERN STANDARD TIME) ON __________________. A
TELECOPY OF YOUR 

                                       55

<PAGE>   56


BALLOT OR A TELEGRAM REFERRING TO YOUR BALLOT WILL NOT BE
SUFFICIENT.

         The holders of Allowed Claims or Interests which are deemed impaired
under a particular plan are entitled to vote to accept or reject such plan. The
Code provides that votes will be counted only if submitted by a Claimant or
Interest holder whose Claim or Interest is scheduled by the Debtor as
undisputed, noncontingent and liquidated, whose Claim or Interest is scheduled
and otherwise of record as of _______ (the last date for filing Ballots), and
who, prior to August 11, 1997, Bar Date has filed with the court a Proof of
Claim or Proof of Interest which is not disputed and has not been disallowed,
disqualified or suspended prior to computation of the vote on the applicable
plan. A Claim or Interest to which an objection has been filed is not an Allowed
Claim or an Allowed Interest unless and until the Court rules on the objection.
Further, the Code provides that the Court may estimate or temporarily allow a
disputed Claim or Interest for purposes of voting on the applicable Plan.

         As a Claimant or Equity Interest holder entitled to vote on a Plan,
your vote is important. In order for the Plan to be accepted and thereafter
confirmed by the Court, 

acceptance of such plan is required by each class entitled to vote on same. A
class of claimants has accepted a plan when holders of one-half (1/2) in number
and two-thirds (2/3) in amount in that class has voted to accept such plan. A
class of Equity Interest holders has accepted a plan when holders of two-thirds
(2/3) in amount in that class has voted to accept such plan. In each instance,
whether the requisite votes have been cast to accept a plan is determined solely
by reference to the dollar amount in the total number of Claims or Interest held
by those of the class that actually voted to accept or reject a plan.

                           XXIX. CONFIRMATION HEARING

         The Bankruptcy Code requires the Bankruptcy Court, after notice, to
hold a confirmation hearing on the Joint Plan. An objection to confirmation may
be filed in accordance with the provisions herein.

         The confirmation hearing on the Joint Plan has been scheduled for
__________ 1998 at _______ AM before Judge James F. Queenan, Jr., of the United
States Bankruptcy Court for the District of Massachusetts, Donohue Building, 595

announcement made at the confirmation hearing to those in attendance. However,

         Counsel to Creditors' Committee

                         XXX. ALTERNATIVES TO THE PLAN

         The Debtor believes that the Joint Plan provides its creditors and
equity security holders with the greatest possible value that could be realized
on their respective Claims and Interests. The alternatives to confirmation of
the Plan are (i) confirmation of an alternative plan of reorganization submitted
by the Debtor or by another party in interest or (ii) liquidation of the Debtor
under Chapter 7 of the Code. Since the Filing Date, the Debtor has been engaged
in extensive negotiations with numerous parties 

                                       58
<PAGE>   58


having interests in the Chapter 11 reorganization proceedings. The Debtor has no
reason to believe that any further negotiations regarding the plan of
reorganization with any of the parties having an interest in the Chapter 11
reorganization proceedings would lead to an alternative plan of reorganization
or plan of liquidation that could be confirmed within a reasonable period of
time without protracted litigation.

         Under Section 1121 of the Code, a Debtor has the exclusive right to
file a plan of reorganization during the first one hundred twenty (120) days
after the commencement of its Chapter 11 case and to obtain acceptance thereof
during the period of sixty (60)days thereafter. The court has entered an order
extending the Debtor's exclusive right to file a plan of reorganization up to
and including December 15, 1997.

         Alternatively, a liquidation of the Debtor could be carried out with
the results described above (Best Interests of Creditors and Shareholders). For
the reasons described, the Debtor believes that the distribution to each
impaired class under the Joint Plan will be greater and earlier than
distributions that might be received after liquidation of the Debtor. The Debtor
believes that 

                                       59

<PAGE>   59


confirmation of the Joint Plan is preferable to the alternatives described above
because the Joint Plan provides for an equitable, early distribution to all
classes of the Debtor's creditors and preserves value for equity security
holders; any alternative to confirmation of the Joint Plan would result in
significant delays in and probable diminution of recoveries.

                        XXXI. RETENTION OF JURISDICTION


         The Bankruptcy Court shall retain jurisdiction with respect to the
Debtor's case pursuant to the provisions of Chapter 11 of the Bankruptcy Code

Equity Consideration.  Each holder of Equity Interests shall receive with
respect to each Equity Interest a Pro-Rata Portion of the Equity Consideration. 
In the case of an Equity Interest that is a Preferred Stock, it will be treated
as if it had been converted to the same number of Common Shares.  In the case
of an Equity Interest that is an Option, the Equity Holder shall pay the option
exercise price separately to the reorganized Debtor, prior to Debtor's payment
of the Equity Consideration therefor.  "Pro-rata Portion" means the per share
number of Equity Interests held by a holder of Equity Interests divided by the
total number of Equity Interests held by all holders of Equity Interests.  For
purposes of determining a holder's Pro-rata Portion, each Option shall be
considered fully vested and exercisable notwithstanding anything to the
contrary set forth in any written agreement between the Debtor and the holder
of the Option (an "Option Agreement") with respect to vesting of such Option.

     (b)  On or before the first anniversary of the Effective Date, Osmonics
shall pay to the Equity Interests Trust, for distribution to the holders of
Equity Interests in accordance with their Pro-rata Portion of said payment, an
amount equal to the sum of (i) ten (10%) percent of the Equity Consideration
minus (ii) the amount of any Set-off Right (as defined below) 

                                      -11-

<PAGE>   12

properly taken by Osmonics plus (iii) interest on the amount paid at
the rate of 8 1/2% per annum from the Effective Date to the date of payment.
                                                                               
     (c) Osmonics shall pay to the Equity Interests Trust $100,000 towards the
costs and expenses of the MSI v. Kenyon & Kenyon litigation (the "K & K
litigation"), which shall be reimbursed first from any recovery in such
litigation.  The Holders of Equity Interests shall also advance $100,000 to the
Equity Interests Trust for the costs and expenses involved in prosecuting the K
& K Litigation.  Such $100,000 shall be taken from the Equity Consideration and
held by the trustee for use in the K & K litigation.  Each holder of Equity
Interests shall receive its Pro-rata Portion of the net amount of any recovery
as a result of the K & K litigation after payment of any costs and expenses
involved in the K & K litigation, reimbursement of the $100,000 advance by
Osmonics, the fees and expenses of the trustee, and payment or provision for
taxes resulting from such recovery.

     (d) (1) Osmonics will have the right to set-off ("Set-off Right") against
the unpaid Equity Consideration any actual damages suffered or expenses
reasonably incurred by it as a result of any breaches of representations and
warranties by Debtor set forth in Exhibit C to this Plan to the extent that
such damages and expenses exceed $100,000.  Neither the Equity 

                                      -12-

<PAGE>   13

Interests Trust nor any holder of an Equity Interest shall have any
obligation to return any portion of the Equity Consideration received by the
holder or the Equity Interests Trust or any liability to Osmonics and/or
reorganized Debtor beyond Osmonics's  Set-Off Right in accordance with this
section, except for liability arising out of any fraud or intentional
misrepresentations by the Debtor.

     (2) Within thirty (30) days after the end of each calendar quarter
following the Effective Date, Osmonics shall give the Equity Interests Trustee
written notice describing in detail any Set-Off Right that Osmonics intends to
exercise and with respect to which a notice has not previously been given.
Osmonics agrees that in the event it becomes consciously aware of any claims or
conditions that would give rise to a Set-off Right, both the Debtor and
Osmonics will act in a commercially reasonable manner (as determined without
regard to Osmonics's Set-off Right) in resolving such claims or responding to
such conditions.

     (e) Termination of Equity Interests.  Upon the Effective Date, all Equity
Interests shall automatically be canceled.

     3.6  Disputed Claims Reserve.

     Ten (10) days after the Effective Date, the distributions 

                                      -13-

<PAGE>   14

reserved for the holders of disputed claims shall be delivered to the 
Disbursing Agent (Debtor's Counsel) but shall be held in a segregated, 
interest bearing account (the "Disputed Claims Reserve") for the benefit of 
holders of disputed claims entitled thereto under the Plan.  At the option 
of the reorganized Debtor, any claim not previously settled may be objected by
filing a written objection within forty (40) days of the Effective Date.
Any claim not objected to by that time will be deemed allowed.  There will
be deposited into the Disputed Claims Reserve an amount of cash which would
have been distributed on account of the disputed claims if all disputed
claims were allowed in the full amount claimed by the holders thereof, plus
an amount of interest estimated by the Disbursing Agent as adequate to pay
the claim, if allowed in full, plus accrued interest.


                ARTICLE IV -  IDENTIFICATION OF CLASSES IMPAIRED

                                UNDER THIS PLAN

     Claims in Classes 1 and 2 are not impaired under the Plan.  Claims in
Classes 3 and 4 and Interests in Class 5 are impaired under the Plan.

     6.1 Upon the Effective Date, each of the leases and executory contracts
set forth on Exhibit C as specifically approved by Osmonics and attached hereto

     6.2 The Debtor reserves the right on behalf of Osmonics to amend Exhibit C
at any time prior to the Effective Date, and the listing of any lease or

lease or contract prior to the Effective Date.  Any party to a lease or
contract which is affected by an amendment to Exhibit C shall be provided
written notice of such amendment and shall have 30 days after the mailing of
such notice to object or make a claim or assertion in connection with such

<PAGE>   28


                   EXHIBIT C TO JOINT PLAN OF REORGANIZATION
In consideration of Osmonics becoming a joint proponent of the Plan, and except
as set forth in the Disclosure Statement filed with the Joint Plan or a
schedule hereto, the Debtor hereby, represents, warrants and covenants to
Osmonics as follows:
     1.1         Corporate Existence and Power.  The Debtor is a corporation
duly incorporated, validly existing and in good standing under the Laws of the
State of New York, without taking into account the effect of the application of
the U.S. Bankruptcy Code, and has all corporate powers and all governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted.  The Debtor is duly qualified to do business as a
foreign corporation and is in good standing in the Commonwealth of
Massachusetts and in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified
would not, individually or in the aggregate, have a material adverse effect on
the condition (financial or otherwise), business, assets, results of operations
or prospects of the Debtor and the Subsidiaries (as defined in Section 1.3),
taken as a whole (a "Material Adverse Effect").  The Debtor has heretofore
delivered to  the Osmonics true and complete copies of the Debtor's articles of
incorporation and bylaws (collectively, the "Organizational Documents") as
currently in effect.
     1.2         Governmental Authorization.  The execution, delivery and
performance by the Debtor of this Agreement and the consummation of the
Acquisition by the Debtor require no action by or in respect of, or filing
with, any governmental body, agency, official or authority other than the
approval of the U.S. Bankruptcy Court for the Western Division of the District
of Massachusetts and possible application of Hart- Scott-Rodino if Debtor's
total assets exceed $10,000,000 at the Effective Date.
     1.3         Subsidiaries.
          1.3.1           "Subsidiary" means any entity of which securities or
other ownership interests having ordinary voting power to elect a majority of
the board of directors or other persons performing similar functions are
directly or indirectly owned by the Debtor.
          1.3.2           Each Subsidiary is a corporation duly incorporated, 
validly existing and in good standing under the laws of its jurisdiction of
incorporation, has all corporate powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted and is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities make such qualification
necessary, except for those jurisdictions where failure to be so qualified
would not, individually or in the aggregate, have a Material Adverse Effect.
          1.3.3           Except as set forth on SCHEDULE 1.3, all of the
outstanding capital stock of, or other ownership interests in, each Subsidiary,
is owned by the Debtor, directly or indirectly, free and clear of any Lien and
free of any other limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests).
          1.3.4           There are no outstanding:
                          1.3.4.1     Securities (as such term is applied in
                 interpreting the securities laws of the United States) of the
                 Debtor, or any Subsidiary, which are convertible into or
                 exchangeable for shares of capital stock or other voting
                 securities or ownership interests in any Subsidiary; and
<PAGE>   29


                          1.3.4.2     Options or other rights to acquire from 
                 the Debtor or any Subsidiary, and no other obligation of the
                 Debtor or any Subsidiary to issue, any capital stock, voting
                 securities or other ownership interests in, or any securities
                 convertible into or exchangeable for any capital stock,
                 voting securities or ownership interests in, any Subsidiary
